Therefore, there is a pressing need for an efficient detection platform to rapidly and sensitively identify <jats:italic>A. portunus<\/jats:italic>. In this study, we have developed a method known as recombinase polymerase amplification combined with lateral flow dipstick (RPA\u2010LFD) for the swift detection of <jats:italic>A. portunus<\/jats:italic>. Three sets of specific primer pairs and a probe were designed according to the spore wall protein (SWP) sequence of <jats:italic>A. portunus<\/jats:italic>, in which one of the primer pair (ApSWP\u2010F1\/R1) showed the best amplification effects. The optimal reaction temperature was ultimately determined to be 39\u00b0C and the optimal reaction time was set at 10\u2009min after careful optimisation of both variables. The sensitivity of the RPA\u2010LFD method was better than that of polymerase chain reaction (PCR), with a limit of 1.71\u2009\u00d7\u200910<jats:sup>\u22124<\/jats:sup>\u2009ng\/\u03bcL. This RPA\u2010LFD detection method has good specificity for the detection of <jats:italic>A. portunus<\/jats:italic>, and tests for other parasites such as <jats:italic>Zschokkella ophiocephali<\/jats:italic>, <jats:italic>Myxobolus drjagini<\/jats:italic>, <jats:italic>Myxidium lieberkuhni<\/jats:italic> and <jats:italic>Pelteobagrus fulvidraeo<\/jats:italic> are negative. The above results show that the RPA\u2010LFD detection method of <jats:italic>A. portunus<\/jats:italic> established in this study has strong specificity, high sensitivity, simple operation and visual results, which can be widely used for rapid detection on
